PURPOSE: A combustor of a hot water boiler is provided to improve the efficiency of combustion because a burner malfunction of a pellet combustor caused by a lack of an air supply for combustion is supplemented by a blower. CONSTITUTION: A combustor of a hot water boiler comprises a pellet combustor(200). The pellet combustor is inserted into a combustion chamber through a second fuel input(120). The pellet combustor comprises a burner(210), a pellet supplying pipe(230), a blowing pipe(240), and a shielding plate(250). The burner is connected to the pellet supplying pipe. The pellet supplying pipe supplies pellets from a hopper(220) to a nozzle(211) of the burner. A screw axis(232) of the pellet supplying pipe is driven by a motor(231). The blowing pipe is installed in one side of the burner. The blowing pipe supplies air required for the combustion to a spraying hole(212) of the burner by an operation of a blowing fan(241). The shielding plate is installed in a pipeline of the blowing pipe and the pellet supplying pipe connected to the burner. When the burner is inserted into the combustion chamber, the shielding plate closes the second fuel input. |
